PolyMem silver dressings are composed of a hydrophilic, polyurethane membrane matrix and semi-permeable, polyurethane, continuous, thin-film backing which is optimized for oxygen and moisture vapor permeability and as a barrier to liquids. They are the only dressings that contain a safe, non-toxic cleanser, a moisturizer, and absorbing agent silver, all in the polyurethane matrix.
- Wound exudate absorbed into dressing liberates silver ions.
- Formulation includes nanocrystalline, small particle silver to protect against microbial contamination.
